7 Homemade Moss Killers For Tarmac Driveways

1. Bleach

At first glance, bleach may not seem like the ideal solution for removing moss from tarmac. After all, this harsh chemical can be damaging to plants, grass, and other surfaces, not to mention it can cause irritation to the skin when using it.

However, when used carefully and in small amounts, bleach can be a highly effective tool for cleaning away unwanted moss and preventing its return. The key to using bleach effectively is to use it at the right concentration.

Since any dilute form of bleach (such as a mixture of bleach and water) may not be strong enough to kill off stubborn moss spores, you should use straight bleach or a solution that contains about 85% bleach.

This concentrated form allows you to get deep into the pores of the tarmac and combat the growth of moss at the source. Another advantage of using bleach for removing moss is that this inexpensive cleaning product works quickly.

Once the bleaching solution has been applied, you will see visible results after just 30 minutes. Of course, repeated applications may be required if new spots of mold continue to appear on your driveway or walkway.

However, by using a regular maintenance application routine, you can keep your tarmac looking clean and moss-free all year long!

2. Ammonia

It is among the most often produced industrial compounds in the United States, with ammonia (NH3) being the most frequent. Ammonia is used to eradicate moss in the same way that bleach would be used in the same circumstance.

Ammonia is corrosive to metals and other organic materials due to its alkaline properties.

Approximately 80% of the ammonia produced by the agricultural industry is used as fertilizer. However, it is also used to manufacture other items, such as pesticides. It is also present in several home cleaning products.

Because ammonia is a gas in its natural state, you would use a product containing ammonia rather than pure ammonia for moss killing.

Important: Be sure to take any necessary safety precautions when using this chemical including wearing gloves and a face mask as ammonia fumes can be harmful if inhaled.

Very corrosiveFumes can be harmful if inhaled

There are two types of vinegar you can use on the tarmac one is cleaning vinegar and the other is white vinegar. If you have a lot of moss on your tarmac we do recommend you use cleaning vinegar.

This is because white vinegar has a 5% acidity, whereas cleaning vinegar has a 6% acidity. The change in acidity might be as little as 1% but, cleaning vinegar is 20% stronger than white vinegar meaning it can handle thicker types of moss.

Take Note: that while vinegar is effective at killing moss on tarmac, it will not prevent new growth from occurring. As such, you may need to reapply this solution on a regular basis in order to keep your tarmac free of moss.
